Thanks for the info.  If that's an Opera signal then
maybe my timing system isn't working so bad after all.

I see.  Hmm, a lot of energy in the carrier!

Hopefully there will be some snippets of pure
carrier at some point so I can see what the
jitter looks like.

I just threw together a live spectrogram covering
137500 +/- 25Hz

Updates about every 15 minutes or so.  You'll probably
have to do shift-refresh to make your browser grab
the latest image.

I'm recording the whole band but only plotting a 50Hz band.

I'll leave this running overnight and see what comes in.
Looking forward to decoding messages from Domenico!
